Sir I have made a draft for the project https://devel.rtems.org/ticket/4272 after some discussion about it on discord and mail-list . I would be highly grateful to get some comments and reviews about it in improving the draft (for example the part related to adding support of newly created scripts in rtems-tools to rtems-test.) https://docs.google.com/document/d/19HeKc6W2ng2X8PoCMVi68A1Z1BbO5D7C0xVHhkgMgBY/edit?usp=sharing . Also since I am little new to this project it will be really helpful if anyone can please point out any basic errors which I may have made in the project description.
